We're dividing 248871 by 26 
The aim is to understand the frequency of 26 in 248871.

Advancing to step 1:
The number 26 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 26

On to step 2:
The number 26 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 26

Let's proceed to step 3:
26 goes into 248 9 times with a remainder of 14.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 234 from 248 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 26

Moving on to step 4:
148 divided by 26 is 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Subtracting 130 from 148 leaves us with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 26

On to step 5:
187 divided by 26 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 957.0
If we subtract 182 from 187, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 26

Going ahead to step 6:
When dividing 51 by 26, we get 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 9571.0
Subtract 26 from 51 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
If we divide 250 by 26, we get 9 and a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 9571.9
Deduct 234 from 250 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
When dividing 160 by 26, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 9571.96
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
26 can be fit into 40 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 9571.961
Deduct 26 from 40 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
When dividing 140 by 26, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 9571.9615
Deduct 130 from 140 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
100 divided by 26 is 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 9571.96153
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
26 goes into 220 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 9571.961538
The remainder is 12 after subtracting 208 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
120 divided by 26 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 9571.9615384
If we take 104 away from 120, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
160 divided by 26 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 9571.96153846
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 9571.96153846, and the remainder is 4e-09.
